    “…We theoretically investigate light absorption by a graphene monolayer that is coated on the outside of dielectric-metal core-shell resonators (DMCSRs). We demonstrate that light absorption of graphene can be greatly enhanced in such multi-layered core-shell architectures as a result of the excitation of the hybridized bonding plasmon resonance supported by the DMCSRs. …”

    “…The main challenges in multienzymatic cascade reactions for CO(2) reduction are the low CO(2) solubility in water, the adjustment of substrate channeling, and the regeneration of co-factor. In this study, metal-organic frameworks (MOFs) were prepared as adsorbents for the storage of CO(2) and at the same time as solid supports for the sequential co-immobilization of multienzymes via a layer-by-layer self-assembly approach. …”
